摘　　要：采用三因素五水平正交试验设计，建立白菜型油菜“９１－１０”的产量与播期、密度和施肥的数学模型。结果表明：施肥对产量的效应最大，但各因素间互作效应明显。降低留苗密度，适期晚播，增施肥料有利于产量的提高。在本地区三因素的适宜范围为：直播期１０月１２～１８日，留苗密度２７～３６万／ｈｍ２，施用尿素３６０～４２０ｋｇ／ｈｍ２。The response model of B campestris yield (CV 91 10 with low erucic and low glucosinolate content) to three culture measures inclnded sowing time, density and fertilizer was established by meanes of modern regression desigen——qnadratic orthogonal rotational design The main and interactive effect of these measures on were identified and the measures were analysed optimally by analogue method of computer on the model The high yield of the B campestris cultivar “91 10” could be ottained by optimal measures which were sowing time: the date October 12￣18, density 2 7￣3 6×10 -4 /hm 2, fertiligzer rate : 360￣420 kg/hm 2
